Robin Good: Wallflux is a tool which helps you to export Facebook Page and Group Walls to RSS 2.0 feeds, which you can then subscribe to in your RSS reader / aggregator for final curation.
Wallflux works for Facebook Groups, Pages and Events and Users.
"When you need to import Facebook group posts, comments & images into your blog, Wallflux is the service of choice with custom #atom-feeds."
Wallflux also integrates a search feature which allows you to search right inside those Facebook Pages ad Groups.
P.S.: Due to privacy settings, Wallflux does not work out of the box for closed or secret Facebook Groups., but with a small action from your side (adding the service to the group) you can access those Wallflux-feeds just like those of regular Facebook Groups.
Note: To prevent abuse there is a charge €5 in handling to enable your closed or secret group.
Wallflux is free.
